PACSystems™ RX3iIC695NIU001GFK-2419M Ethernet Network Interface UnitMarch 2009The PACSystems RX3i Ethernet NIU, IC695NIU001,makes it possible to use PACSystems RX3i and Series90-30 I/O remotely on an Ethernet network. Once set upby configuration, data exchange is completely automatic.System control can be provided by any GE Fanuc masterdevice capable of exchanging Ethernet Global Data. TheEthernet NIU automatically provides the controller withstatus information in each exchange. The applicationprogram logic in the controller can monitor this status data,and issue appropriate commands to the Ethernet NIU.An RX3i Ethernet NIU station consists of:▪ an RX3i Universal Backplane (IC695CHS0xx)▪ an RX3i power supply (IC695PSxxxx)▪ the RX3i Ethernet NIU (IC695NIU001)▪ one or more RX3i Ethernet modules (IC695ETM001)▪ proprietary application software▪ Optional Series 90-30 expansion backplanes.▪ PACSystems RX3i and/or Series 90-30 modules, asappropriate for the application.The Ethernet NIU is compatible with the same types ofmodules, backplanes, and other equipment as aPACSystems RX3i CPU. For a list of compatible products,see the PACSystems RX3i Hardware and InstallationManual, GFK-2314.This module requires Machine Edition Logic Developersoftware, version 5.51 or later.Ethernet NIU Features▪ 20Kbytes of optional local logic. Supports alllanguages except C programming.▪ 10 Mbytes of built-in flash memory for local user datastorage.▪ Battery-backed calendar clock.▪ In-system upgradeable firmware.▪ Two serial ports: an RS-485 serial port and anRS-232 serial port.▪ Supports Ethernet communications via the backplane-based Ethernet Interface module (IC695ETM001)▪ Data exchange using Ethernet Global Data (EGD)▪ TCP/IP communication services using SRTP▪ Comprehensive station management and diagnostictools▪ Supports operation with redundant controllers▪ PACSystems RX7i and RX3i controllers can sendselected COMMREQs to the RX3i ENIU via EthernetGlobal Data. The ENIU executes the COMMREQs andreturns the results to the controller.▪ During EGD configuration, RX3i Ethernet interfaces areidentified by their Backplane/Slot location.NIU OKNIU SCANNING I/OOUTPUTS ENABLEDI/O FORCEBATTERYSYSTEM FAULTRESETNIU001COM 1COM 2BATTCOM1 ACTIVERUN OUTPUT DISABLESTOPRUN I/OENABLECOM1 ACTIVEEthernet Global Data FeaturesThe Ethernet NIU communicates with its controller viaEthernet Global Data exchanges. One exchange is used tosend outputs to the ENIU and another exchange is used tosend inputs back to the controller. The ENIU supportsreceiving outputs from redundant controllers. By sending theEGD exchange to a group address both controllers canreceive the inputs. Up to 1300 bytes of outputs can be sent toa set of ENIUs from a controller. Each ENIU can send up to1300 bytes of inputs to the controller.A typical system might consist of a controller with five ENIUs.The controller sends 1300 bytes of outputs and each ENIU |
